lo'mZZ whom, it I'm/11y concern:

Be it known that I, HENRY 0. Porn, a citizen of the United States, residing at. Claude, in the county of Armstrong and State of Texas, have invented new and useful. improvements in Cultivator Attachments, of which the follor'ving is a specification.

My invention relates to cultivator attachmerits; and more particularly to an attachment to be connected to alister orother plow and to be used incleaning grass; weeds, or the like from the drills or rows. after the planting of the ground.

My invention consists, broadly, in a pair of cutting blades or knives adapted to be adjustably connected to the lister-bear'n after the plow-blades have been removed and after the planting ofthefield, and theseknives are adapted to straddle the center row and to work down to three inches. under the surface of the ground, extending half-way to the adjoining row on both sides of said center row, thus absolutely killing all grass, weeds, or the like, and'turningup just enough dirt to cover the scrub. .By. thustreating each row in succession a field may be cleared more quickly, more easily, and more thoroughly by my improved attachment than by any implement in use My'invention also consists in certain 'in provement's hereinafter described in detail, reference b ing oads to the accompanying drawings, in which' vFigure 1 is a side elevation ot-theinvention. Fi 2 is a front elevation, and Fig. 3 is a rear elevation.

Referringto the figures, 1 represents the lister-bea'm with the upper and lower trans- I versely-extending openings 2 and3,jr espe ct'ively. I j 4 4 and 5 represent, respectively, the inner' and outer blocks, disposed onboth sides of the beam 1' and connected adjacent their upper ends to the beam 1 by means of the bolt 6, passing transversely through them and through the upper opening 2- of said beam.

7 and -8' are the cutting blades or knives disposed to the rear of the beam 1 and provided with the upturned portions 9 at an angle to said knives, and providedwith curved slots 10 centrally thereof. '-The upturned portions 9 of saidknives are connected to the beam l by means of bolt 11, passing through the lower opening 3 ofsaid beam andalso through the inner and outer blocks 4 and 5. and working in the slots 10 of the upturned portion 9, so that by loosening the bolt 11 the knives may be adjusted with relation to their angle toward the surface of the soil.

12 is a bolt connecting'the upturned portions 9 of the-knives in advanceof the beam adapted to be connected to the beamof a lister or other plow, a pairof cuttingblades having upturned portions on one end provided with curved slots, a bolt assing transversely through said beam. anc operating in said slots, whereby an angular adjustment of said cutting-blades may be had, blocks disposed between said beam and said upturned portions through which saidibolt also passes. a pivotal connection between the blocks and the upturned portions, a forward bolt 0011- necting said upturned portion in advance of said beam, a bearing-plate disposed across said upturned portions in the rear of said beam, and eyebolts connecting said bearingdescribed. a v
